How can I defend myself against a wrongly-issued parking ticket?

I paid £9 at Oxford station ticket office for a car parking ticket and the receipt was timed at 9.25am. I travelled to London by train and, on my return, found that I had a Civil Parking Notice from APCOA timed at 10.55am saying I had not paid for my parking. I sent APCOA copies of the receipt and notice, indicating the disparity in times. They replied by letter stating that I had not paid for my parking place and should send them £50. Is there any further action you would recommend on my part?

Update: I advised PH to challenge them to take him to court where he would vigorously defend himself and would countersue for his time wasted at an hourly rate. APCOA then backed down.
